Over the past 19 years electrode configuration has evolved.

"Series" indicates what sort of electrodes your "SilverPuppy" generator uses.

"Series 2":  12 gauge wire, 7" total length, bent into U shape and adapted with Brass Ferrule to 2.5mm diameter to fit tight in the electrodes sockets. [as shown in photo]  [up to 1/1/2015]

 Specs for  all:

.9999 Fine Solid Silver

price is for a pair.

Electrodes can be shipped Internationally via 1st Class mail for less [ roughly 1/2 price ] but I won't know how much less till I get the label made out.

If you want them sent 1st Class, pay what the cart charges and Type "Send 1st Class" in Order Comments...I will refund the difference.
